As the main source of dust in Asia, China often suffers from events. The temporal and spatial characteristics events change with variations geography, climate human activities. Based on criteria selecting proposed recently by Environmental Monitoring Station, hourly concentration PM10 PM2.5 336 cities 2015 to 2020 were used study more accurately objectively. results showed that all clearly decr...

The nearby Mira-like variable L2 Pup is shown to be undergoing an unprecedented dimming episode. The stability of the period rules out intrinsic changes to the star, leaving dust formation along the line of sight as the most likely explanation. Episodic dust obscuration events are fairly common in carbon stars but have not been seen in oxygen-rich stars. We also present a 10-μm spectrum, taken ...

High desert dust concentrations raise concerns about adverse health effects on human populations. Based on a systematic literature review, this paper aims to learn more about the relationship between desert dust and human health in the world and to analyse the place of West Africa as a study area of interest. Papers focussing on the potential relationship between dust and health and showing qua...

Sea salt and mineral dust records as represented by Na and Ca concentrations, respectively, in Greenland and Antarctic ice cores show pronounced glacial/interglacial variations. For the Last Glacial Maximum (LGM) mineral dust (sea salt) concentrations in Greenland show an increase of a factor of approximately 80 (15) compared to the Holocene and significant shifts by a factor of 15 (5) during D...

The paper describes the performance of the Dust Regional Atmospheric Model (DREAM) after being nested within the National Centers for Environmental Prediction (NCEP/eta) operational weather model. The model system is designed to simulate dust entrainment, transport, and concentration under changing atmospheric and terrestrial conditions to better forecast dust episodes that impose health outcom...

The source of the large amounts of dust observed in high redshift galaxies has remained uncertain for nearly 40 years. Despite the success of models in producing dust within supernova explosions, only a handful of supernovae show direct observational evidence for dust condensation, and these examples all yield 2-3 orders of magnitude less dust than predicted by the models. Recent observations s...

Global climate is in part affected by airborne particles known as dust aerosols, which are abundant in dry deserted areas such as the northwestern region of Africa. Researchers have found that dust aerosols can travel long distances, even across continents, to participate in the life cycle of other ecosystems. However, in spite of dust aerosols being good for nature, elevated concentrations and...

as surfactants enhance the membrane transport of organic compounds, it has to be assumed that they decisively influence the absorption of pollutants from house dust. sampling sites for the surfactant analysis include housing areas, each location of which has different surroundings such as rural, urban, construction, and industrial area. three stations had been selected for each housing area and...

the aim of this study is to determine the area affected by dust storms in different wind speeds using satelliteimages. in the first step, windy conditions of the sistan plain were analyzed using wind statistics data. next, fivestormy days of zabol city, indicating different wind speeds and horizontal visibilities during those storms, wereselected. then, high temporal resolution modis data was u...

This study aims to determine the mineral contribution to PM10 in the central Mediterranean Sea, based on 7 yr of daily PM10 samplings made on the island of Lampedusa (35.5 N, 12.6 E). The chemical composition of the PM10 samples was determined by ion chromatography for the main ions, and, on selected samples, by particle-induced X-ray emission (PIXE) for the total content of crustal markers. Ae...
